Outer size(section) 24x12mm; inner size approx 13x9mm;
I tried Ender 3 Cable Chain(by johnniewhiskey), it was a good one and i like this concept, easy to maintain my cable, but not strong enough for horizontal movement on my custom corexy. I prefer the Ultimaker2 Cable Chain(by sneakypoo) side wall and connection design, but the bottom i think is a little bit weak against pushing and the deformation from the side wall. So i build my own model to mix the feature i need and here we are.
